Fundus imaging –a need
of the times for Indian
Optometry clinics
Part 1

Digital imaging
Is it relevant to Indian
optometrist?

Digital imaging
• Is it relevant to Indian
optometrist?
• Answer is YES
Let us see
HOW

Presentation has 4 components
(and is uploaded in 2 parts)
• Why is imaging required
• Just a touch :
Glaucoma/ diabetic retinopathy
• How is fundus imaging possible in
Indian optometry clinic
• What are the benefits

Primary Causes of blindness in India

Optometrist can help in managing
avoidable blindness-Which is over 75%
(Direct management/ early detection)

Approx 50%+ component is
unoperated cataract

Approx 21% uncorrected
refractive error
unoperated cataract
Approx 13% glaucoma

refractive error
unoperated cataract
Approx 13% glaucoma
Approx 5% diabetic retinopathy
(and 26% of avoidable blindness)

What does it mean to be visually
impaired
• Indian optometrist is sensitive to this question
• We know that visual impairment & poverty
support each other
• Bread-earning opportunities & social standing,
both are adversely affected with poor visual
performance
• Optometrist plays a vital role in noble cause of
fight against blindness: few examples follow

Every optometrist is concerned if someone
suffers due to avoidable visual impairment
Tailor

What happens
when this
tailor goes old
Tailor Prosperity

What happens
when this
tailor goes old
Poverty

A sample study: 64% people are
driven into poverty within 5
years of having been struck blind
A village tailor loses prosperity
just because of uncorrected
presbyopia

Glaucoma
A young
professional can
not drive to office
because of
glaucoma

Diabetic retinopathy
Today, optometrists are
“important & needed”
in eradicating “needless” blindness
by the year 2020 as per goals of
VISION-2020

VISION-2020
It is already too late to sit around &
wait for somebody to do
something, someday.

Something is
what this
presentation
suggests

We do direct ophthalmoscopy in
routine

Why do we dilate for fundus exam?

Why do we dilate for fundus exam?
Optometrist does not dilate
pupils in India
To view wider zone

To manage glaucoma/DR/HR/Other
retinal or corneal lesions
• We need to compare the findings of present
day with those of older encounters

• There is no better way than to have images

• Recordings of ophthalmoscopy are based on
skill and memory
• Direct ophthalmoscope gives approx 6 to 8
degrees of zone

• We need to compare the findings of present day with
those of older encounters
• Recordings of ophthalmoscopy are based on skill and
memory
• Direct ophthalmoscope gives approx 6 to 8 degrees of
zone
• Indirect gives wider range but needs dilation
& consumes lot of time
• Non-mydriatic camera gives upto 40 degrees of
coverage in few seconds and can image eye-surface
also

Non-mydriatic camera gives upto 40 degrees
of coverage in few seconds and can image
eye-surface also

The non mydriatic camera
• Is an alternative or complement to
ophthalmoscopy by imaging
fundus and also eye-surface

While glaucoma can have a battery of
tests, imaging the ONH is important

• Why on earth are we concerned
about it & that too in India
• Yes…

• Why on earth are we concerned about it &
that too in India
• Yes…
• This is a time-bomb that is ticking for World,
for Asia and more important to us FOR INDIA
• Let us understand the
gravity of situation first

• Sooner or later, every diabetic will have
diabetic retinopathy (DR). Usually after 10
years of standing diabetes
• This means that blindness due to DR is directly
proportional to number of diabetics

• Sooner or later, every diabetic will have
diabetic retinopathy (DR). Usually after 10
years of standing diabetes
• This means that blindness due to DR is directly
proportional to number of diabetics
• People with DM are at risk of losing vision. We
may delay or prevent DR effects by medical
management of DM & with lasers BUT we can
not reverse the harm that DR may have done.

Diabetic retinopathy- Numbers
• In world: Comparison between
2010 data & projected 2030
figures, there will be an increase
of 54% diabetics
(will be around 440 million)

Diabetic retinopathy- Numbers
• In world: Comparison between 2010 data &
projected 2030 figures, there will be an
increase of 54% diabetics
(will be around 440 million)
• That means for every 2 diabetics, there will be
3 diabetics by 2030
• This will not be uniform. Higher percentage is
expected in poorer countries
• See the chart that follows

Expected increase in number of
people with diabetes: 2010 to 2030

Expected increase in number of
people with diabetes: 2010 to 2030
While rest of the world will have
a 54% increase, India will have
72% increase in diabetic
population

How big is
Diabetic Retinopathy
• 2010 Dr Rajiv Raman, senior
consultant, Sankara
Nethralaya. : India, the
world's diabetes capital, has
another reason to worry.
Diabetic retinopathy is the
sixth cause of blindness in the
country. "From being the 17th
cause of blindness in the
country 20 years ago it has
become the sixth cause with
18% of diabetics above 40
having diabetic retinopathy.
This is a cause of worry,"

What is diabetes
Insulin that is secreted by cells in pancreas
manages blood sugar control mechanism. In
diabetes this control malfunctions & causes
high blood sugar levels

What is diabetes
Type 1 diabetes
• Uncommon: caused by
destruction of insulin-
secreting cells

What is diabetes
Type 1 diabetes
• Uncommon: caused by
destruction of insulin-
secreting cells
Type 2 diabetes
• Develops slowly, with
age, urban life-style &
has close association
with obesity

In Diabetic Retinopathy (DR)
Both types of Diabetes
mellitus cause
complications, especially
due to damage to small
blood vessels
